PYBPHOBOUS LIGHTER.

Specification of Letters Patent.

Patented J an. 13,1914.

l Application filed April 25, 1913. Serial No. 763,492.

To all 'whzfm 'it may concern: Y

Be it known that I Louis V. ARoNsoN, a

tates, 'and a resident of Newark, in the county of Essex and State of i New Jersey, have invented certain new and: useful Improvements in Pyrophorous L1ghters, of which the following is a speciicationi The invention relates to pyrophorous; lighters, viz z-lighters in which a'spark 1sE produced in proximity to a suitable fuel by rubbing or scratching with a metal striker a; spark producing material such as cer1um.

iron or the like.

It relates more particularly to lighters iny which. the fuel is contained in the lighter casing or in the striker itself and in which the material employed as fuel is a solidified hydrocarbon or the like such as solidified gasolene, petroleum, etc.

The invention'has for its object to simplify the construction and operation of such apparatus, and to provide a positive feed of thefuel material to the striker.

rlhe nature of the'invention will be best understood when described in connection with theY accompanying drawings, in which- Figure 1 is an elevation of the improved li liter. Fig. 2 isa vertical section thereof. lFigp is a vertical section illustrating a fuel containing striker. Fig. l is a vertical section of a modified form of the lighter. lFig. 5 is a plan thereof. Fig. 6 is a part transverse section, on an enlarged scale, taken on the line 6-6, Fig. d.

Similar characters of reference designate corresponding parts throughout the several views. Y

Referrin to the drawings, 10 designates a hollow el container tor the solidifded fuel and carries preferably at itsy bottom or side a-strip of the pyrophorous material 11 against which the suitably sharpened end 12 of a striker 13 is adapted to rub or scratch' to cause sparks for the ignition ot the fuel, as is well understood. rlFhe container consists ot an outer shell 14 and an inner shell 15 snugly tting therein and providing a closed container, the two shells being securedpagai'nst vaccidental separation by pro viding a slight indentation 16 in the inner shell and an inward projection 17 adapted to snap therein on the outer lshell. When it 1s deslred to fill the container with the fuel,

the two shells may be readily se arated byv exerting a sli ht force to draw t em apart.

Centrally isposed within the container 'and extending longitudinally thereof to near the bottom of the same is a tubular member 18 provided with an external thread 19 and secured to the top of the inner shell 15 but rotatable with respect thereto. Mounted to turn about this tubular member isa washer or plunger 20 threaded internally to fit the threads 19 of the tubular. member and non-circular or of such a shape with respect to the inner shell 15 that it can not rotate with respect thereto but may on1y reciprocate therein as the member 18 is turned accordingly. To turn this member within which is adapted to t' the'striker 13 lclosing the upper end thereof, it is necessary merely to force the striker sufficiently to insure ay snug t, the end thereof being made conical for this purpose, and then turn the striker. To further insure the turning of the same, slots 21 may be provided in the end of the tubular member projecting beyond the casing and into which correspondin pins 22 extending outwardly from the striker may be inserted. As the striker is thus turned, and with it the said tubular member, plate 20 is advanced and forces the solidified fuel toward the-bottom of the casing where it accumulates upon the inner end 12 ofthe striker which is preferably niade in the form of ahard metal scoop or the like with a sharp striking edge. Above this scoop 12,' the striker may be provided, furthermore, vvith a series of horizontal grooves23 to retain the fuel.

lin using the improved lighter, the striker,

gery in the use of these lighters greatly lesember therein sened, but the recharging of the fuel will be less frequently required. In fact, Where the former style withl ordinary use requires recharging at short intervals, the present form would not require recharging for long periods. y

In Fig. 3, I have shown the striker itself as containing the fuel. For this purpose, the striker consists of an outer casing 30 providing a fuel container and surrounding a centrally disposed threaded rod, or as herein illustrated merely two twisted Wires 31 terminating beyond the casing in a knurled head 32. A removable plug 33 surrounds this rod and is locked to the casing as by means of pins and slots; and, moreover, sealsthe one en d of the saidcasing. The other end of the casing is closed except for a ring of perforations 34 and a central annular opening 35 about a hard metal striking member 36, provided with a sharp striking edge. A Washer or plunger 37 fits about` the threaded rod 31; and the said Washer is threaded internally and of such a shape with respect to the inner Wall of the casing that it cannot rotate with respect thereto but only reciprcates within the shell as the rod 31 is turned accordingly in turning the head 32. The fuel is thereby forced out through the perforations 34 and annular openings 35 in the desired quantity and ignited when the striker end 36 is rubbed along or scratched upon the pyrophorous material. Y i

In Figs. 4, 5 and 6 I have disclosed a modified form of the lighter shown in Figs. 1- and 2, the inner shell 15 being replaced by a short friction top or cap 51 secured to the tubular member 18 which is rotatable relatively thereto, but in one direction only. The rotation is effected by means of a Washer 52 with milled edge, 'said washer being located above the top of the cover 51 and projecting slightly beyond its edge s0 that the same may be conveniently grasped. To prevent the member 18 from beingtoo readily turned and to control the feed motion of the plunger 20, ratchet teeth 53 have been provided at the upper portion of the member 18 within the cap 51, said teeth being adapted to be engaged by a pawl` member 54, preferably as a tongue cut from the wall of the said cap or lid 51. The striker member is shown as fitting the outer end of tubular member 18 merely by friction as the turning of said member is not in this embodiment necessarily effected by the turning of the striker, but preferably by the milled washer 52.

With the hereinbefore described constructions', the fuel is fed as required; 'and particularly with the constructions illustrated in Figs. 4 to 6, the feed may be adjusted with great nicety.
